Leupold’s GX-II has all the features of the GX-I, plus is the only golf rangefinder to provide accurate ranging information that matches your personal striking distances to the slope of the course and current atmospheric conditions. Two more proprietary technologies are merged in this unit: Club Selector and TGR™. Leupold’s Club Selector™ relies on the striking distance of each golfer to determine the appropriate trajectory of the ball to give the most accurate horizontal distance possible. TGR™ combines the information from Club Selector with uphill or downhill slope, elevation and temperature, to fine tune this distance to a level no other rangefinder can match. The result is incredibly accurate ranging, no matter what the conditions, customized for your game.
